You are not so far from your goal! I have also applied Viterbi algorithm over the sample to predict the possible hidden state sequence. With the Viterbi algorithm you actually predicted the most likely sequence of hidden states. The last state corresponds to the most probable state for the last sample of the time series you passed …

Web12 de nov. de 2024 · 792 5 14. HMMs are used when you need to assign one label for each item in a sequence. In sentiment analysis, you assign a single label to the whole sequence (the review), so HMMs are not very appropriate for this task. Instead, you can turn to a Naive Bayes classifier (as in this blog post). Both HMMs and Naive Bayes can be learned … Web29 de nov. de 2024 · We will first initialize a 5×5 matrix of zeroes. After that, we will add 1 to the column corresponding to ‘sentence’ on the row for ‘this’. Then another 1 on the row for ‘sentence’, on the column for ‘has’. We will continue this process until we’ve gone through the whole sentence. This would be the resulting matrix:
